What is the answer to 5x-11=34

The average of 15, 12, 14, 11, and 13 is 13, calculated using the mean averaging method.


Step-by-Step Solution to Find the Average

1. Identify the averaging method:

In this case, you asked for the "average," which generally refers to the mean. The other options provided, "median" and "mode," represent different averaging methods.

2. Calculate the mean:

To find the mean, we add all the numbers and then divide by the total number of numbers:

(15 + 12 + 14 + 11 + 13) / 5 = 65 / 5 = 13

3. Conclusion:

Therefore, the average of 15, 12, 14, 11, and 13 is 13, calculated using the mean averaging method.

4. (Optional) Explain other mentioned methods:

Median: The median is the middle number when the numbers are arranged in order. In this case, 12, 13, 14, 15, and 11. So, the median is 13.

Mode: The mode is the most frequent number. In this case, all numbers appear only once, so there is no mode.

The average of the given numbers is 13.

The average of the given numbers: 15, 12, 14, 11, 13 is calculated by adding all the numbers together and then dividing by the count of numbers. This method is known as the arithmetic mean.

First, we add all the numbers:

15 + 12 + 14 + 11 + 13 = 65.

 Next, we count the number of values, which is 5.

Now, we divide the sum by the count:

Average = 65 / 5 = 13.

Therefore, the average of the given numbers is 13.

The method used to find this answer is the arithmetic mean, which is also known as the Average or Mean method. In the given options, the correct term for the method used is Mean. The other options, Drop Zone 1, Drop Zone 2, Median, and Mode, refer to different statistical measures and are not applicable in this context for finding the average.

Answer:

Option B

Step-by-step explanation:

As shown at the graph:

The circle C ⇒ has a center at (0,0) and radius = 2

The circle C' ⇒ has a center at (0,0) and radius = 7

Circle C shown below was dilated with the origin as the center of dilation to create Circle C'

As the radius of Circle C' is greater than the radius of Circle C ⇒ so, this represents enlargement dilation.

So, the factor of dilation = 7/2

So, the rule will be [tex](x,y) \rightarrow (\frac{7}{2}x,\frac{7}{2} y)[/tex]

The answer is option B

Answer: The answer has to be B.) its facts!

Final answer:

The range for the cost of the plumber's services, represented by the function f(x) = 50x + 25, starts at $25 and extends to infinity, as the number of hours worked can vary.

Explanation:

The question pertains to finding a possible range for the cost of a plumber's services, where the plumber charges a $25 service fee and $50 per hour. The total cost is represented by the linear function f(x) = 50x + 25, with x representing the number of hours worked. The range of this function would be all possible values that the total cost f(x) can take.

Since the number of hours x cannot be negative, the smallest value of x is 0, which would result in the minimum cost, the service fee of $25. Therefore, the range of f(x) starts at 25 and extends to infinity because there is no upper limit on the number of hours a plumber might work, theoretically. The range can be written as {f(x) | f(x) ≥ 25}, which means the set of all f(x) such that f(x) is greater than or equal to 25.

Answer:

y = ㏒₃ x

Step-by-step explanation:

Given: the points (0.33, -1), (1, 0), and (3, 1)

We will check which function goes through the previous points

we will use the point (3,1)

1) y = ㏒₀.₄ x

㏒₀.₄ x = ㏒₀.₄ 3 = -1.199 ≠ 1

2) y = ㏒₁ x

㏒₁ x = ㏒₁ 3 ⇒ unlogic  condition

3) y = ㏒₃ x

㏒₃ x = ㏒₃ 3 = 1

4) y = ㏒₁₀ x

㏒₁₀ x = ㏒₁₀ 3 = 0.477 ≠ 1

So, from the previous explanation:

The function is y = ㏒₃ x

Another solution;

by drawing the four function we will find which function goes through the points (0.33, -1), (1, 0), and (3, 1)

See the attached figure.

So, the answer is y = ㏒₃ x

Step-by-step explanation:

Jessica's rate could be any rate greater than 0.1765 tiles per minute.

To determine Jessica's rate, we first find Meg's rate by dividing the number of tiles laid by the time taken: [tex]\(Rate_{\text{Meg}} = \frac{15 \, \text{tiles}}{50 \, \text{minutes}} = 0.3 \, \text{tiles per minute}\).[/tex] Since Jessica works at a faster rate per tile than Meg, her rate is greater than 0.3 tiles per minute. To calculate the minimum rate Jessica could have, we consider the case where she completes one tile in 85 minutes: [tex]\(Rate_{\text{Jessica}} = \frac{1 \, \text{tile}}{85 \, \text{minutes}} \approx 0.0118 \, \text{tiles per minute}\)[/tex]. Therefore, Jessica's rate could be any value greater than 0.0118tiles per minute.

The rate Jessica could have falls within the range of 0.0118 to 0.3 tiles per minute, as she is working at a faster rate than Meg. The provided answer, 0.1765 tiles per minute, is within this range. Jessica's rate per tile is not limited to any specific value, but it must be greater than Meg's rate of 0.3 tiles per minute. In summary, Jessica could work at any rate greater than 0.0118 tiles per minute, making 0.1765 tiles per minute a valid option.

Step-by-step explanation:

Let the measure of required angle be x degree

[tex] \therefore \tan \: x = \frac{45}{28} \\ \\ \therefore \tan \: x = 1.60714286 \\ \\ \therefore \: x = {\tan}^{ - 1} (1.60714286) \\ \\ \therefore \: x = {\tan}^{ - 1} ( \tan \: 58.109 \degree) \\ \\ \huge \red{ \boxed{\therefore \: x = 58\degree}}[/tex]

Thus, first option is the correct answer.

The results of the expression are given by;

\[tex]\mathbf{log_3(27) = 3}\\\\\mathbf{log_{11}(121) = 2}\\\\mathbf{log_{5}(125) = 3}\\\mathbf{log_{2}(128) = 7}\\\mathbf{(a) log_3(27)}\\[/tex]

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Expressions can be expressed using logarithms;

Express 27 as 3³

[tex]\mathbf{log_3(27) = log_3(3^3)}[/tex]

Apply law of logarithm;

[tex]\mathbf{log_3(27) = 3log_3(3)}[/tex]

So,

[tex]\mathbf{log_3(27) = 3\times 1}\\\mathbf{log_3(27) = 3}\\\mathbf{(b)\ log_{11}(121)}[/tex]

Express 121 as 11³

[tex]\mathbf{log_{11}(121) = log_{11}(11^2)}[/tex]

So, we have:

[tex]\mathbf{log_{11}(121) = 2\times 1}\\\mathbf{log_{11}(121) = 2}\\\mathbf{(c)\ log_{5}(125)}[/tex]

Express 125 as 5³

[tex]\mathbf{log_{5}(125) = log_5(5^3)}[/tex]

Apply law of logarithm;

[tex]\mathbf{log_{5}(125) = 3log_5(5)}[/tex]

So, we have;

[tex]\mathbf{log_{5}(125) = 3\times 1}\\\mathbf{log_{5}(125) = 3}\\\mathbf{dc)\ log_{2}(128)}[/tex]

Express 128 as 2^7;

[tex]\mathbf{log_{2}(128) = log_2{2^7}}[/tex]

Apply law of logarithm;

[tex]\mathbf{log_{2}(128) = 7log_2{2}}[/tex]

So, we have;

[tex]\mathbf{log_{2}(128) = 7\times 1}\\\mathbf{log_{2}(128) = 7}[/tex]

Step-by-step explanation:

For this equation you go left to right because all you have is addition and subtraction, and they are equal in PEMDAS (Parenthesis, exponents, multiplication, division, addition and subtraction)

Since we go left to right we start wtih 200-100

200-100=100

Now we do the last step

Hey there!

Our goal is to create the slope intercept equation for line W, which requires two things that we need to find out: the slope and the y-intercept.

We see that Line W is parallel to line V. Therefore, they have the same slope. So, the slope of Line W is 10/7.

Now, we need to find the y-intercept. To do this, we will plug the slope and the point we are given into the slope intercept equation and solve for b.

-3= 10/7(-3)+b

-3= -4 2/7+b

b=1 2/7

Now, we plug this into our final slope intercept form.

y=10/7x+1 2/7

Answer:

4 mph

Step-by-step explanation:

Givens

Current = c = 2 mph

Alberta = r = ?

d = 2 mph upstream

d1 = 6 mph downstream

Formula

d = r * t

The time is the same so the formula becomes d/r = t

2/(r  - 2) = 6/(r + 2)    

Solution

Cross Multiply

2*(r + 2) = 6*(r - 2)

2r + 4 = 6r - 12                      Subtract 2r from both sides

4 = 6r - 2r - 12                       Combine the right.

4 = 4r - 12                             Add 12 to both sides.

4 + 12 = 4r

16 = 4r                                  Divide by 4

16/4 = 4r/4

r = 4

Answer:

a=4, b=5/2

Step-by-step explanation:

Assuming the given equation is

[tex]a(x + b) = 4x + 10[/tex]

We expand the left hand side to get:

[tex]ax + ab = 4x + 10[/tex]

If this equation must have infinitely many solutions, then

[tex]ax = 4x \\ \implies \: a = 4[/tex]

Also we must have

[tex]ab = 10[/tex]

Put a=4 to get:

[tex]4b = 10[/tex]

[tex]b = \frac{10}{4} = \frac{5}{2} [/tex]

Answer:

x=2

Step-by-step explanation:

Since they are both equal to y set them equal to each other: 2x-3=-8x+17

Subtract 17 from both sides: 2x-20=-8x

Subtract 2x from both sides: -20=-10x

Divide both sides by -10: 2=x

Answer: x = 2 and y = 1

Step-by-step explanation: What we have here is a pair of simultaneous equations and we have been instructed to solve by using the substitution method.

The equations are

y = 2x - 3 ------(1)

y = -8x + 17 ----(2)

The y variable has a coefficient of 1 in both equations so we can start with either of equation (1) or (2).

From equation (1) y = 2x - 3. Substitute for the value of y into equation (2)

2x - 3 = -8x + 17

By collecting like terms we now have

2x + 8x = 17 + 3

(Remember that when a negative value crosses to the other side of the equation it becomes positive and vice versa)

10x = 20

Divide both sides of the equation by 10

x = 2

Having calculated the value of x, we can now substitute for the value of x into equation (1)

y = 2x - 3

y = 2(2) - 3

y = 4 - 3

y = 1

Therefore, x = 2 and y = 1.

Answer:

You are right! The answer is c.

Step-by-step explanation:

Check the picture below.

let's recall that once we move an angle in the opposite direction of the 0-line or x-axis, we end up with a negative counterpart angle.

since we know that θ is on the IV Quadrant, then its negative counterpart must be across the line, and tangent is negative on the IV Quadrant, and positive on the I Quadrant.

If 270°<θ<360°, and tan⁡ θ= - 1/2, then the value of tan(-θ) is 1/2.

Let's start by understanding the given information. We are given that the angle θ lies between 270° and 360°, which means it is in the fourth quadrant of the unit circle. In this quadrant, both the sine and tangent functions are negative, while the cosine function is positive.

We are also given that tan(θ) = -1/2. To find the value of tan(-θ), we can use the identity for the tangent of a negative angle:

tan(-θ) = -tan(θ).

Now, let's find the value of tan(θ) using the given information. We know that tan(θ) = -1/2, and since θ is in the fourth quadrant, we can construct a right-angled triangle in which the opposite side is -1 and the adjacent side is 2. By applying the Pythagorean theorem (a² + b² = c²), we can find the length of the hypotenuse, which is

√(1² + 2²) = √5.

Now, we have all the information to find the value of tan(-θ) using the tangent identity for a negative angle:

tan(-θ) = -tan(θ).

Substituting tan(θ) = -1/2, we get:

tan(-θ) = -(-1/2) = 1/2.
